2-(2-Phenoxyphenylimino) imidazolidine and related compounds (IV and XII) were synthesized and evaluated for hypotensive activity in rats. Most of the 2-aryliminoimidazolidines (IV) were synthesized via the aniline derivatives (VI) by two different methods. Some imidazolidines (IV) were found to be significantly active, with 2-(5-chloro-2-phenoxyphenylimino) imidazolidine (IV-19) being more active than prazosin, the reference compound. The mechanism of action of IV-9 may involve the blockade of peripheral α-adrenergic receptors. This paper describes the synthesis, pharmacology, and structure-activity relationships of the 2-(2-phenoxyphenylimino) imidazolidines.
2-(2-苯氧苯基亚胺)咪唑啉及其相关化合物(IV和XII)已被合成并在大鼠中评估其降压活性。大多数2-芳基亚胺咪唑啉(IV)通过两种不同方法由苯胺衍生物(VI)合成。一些咪唑啉(IV)显示出显著活性,其中2-(5-氯-2-苯氧苯基亚胺)咪唑啉(IV-19)的活性甚至超过了参考化合物哌唑嗪。IV-9的作用机制可能涉及阻断外周α-肾上腺素能受体。本文介绍了2-(2-苯氧苯基亚胺)咪唑啉的合成、药理学及构效关系。
